What is QSPSC

QSPSC Concrete Quality

+ = Management System

ISO 9001 Model

Characteristics of QSPSC

¢ Local scheme specific for Hong Kong construction projects

¢ Pair with ISO 9001 ¢ Tailor-made for concrete suppliers

Information of QSPSC

¢ All existing commercial concrete batching plants in Hong Kong are applying QSPSC

¢ QSPSC has 15 years history ¢ The first issue of QSPSC document was

published on 28th September 1991 ¢ The first QSPSC certificate was issued on 29th

April 1992 ¢ Existing No. of certificates - around 60 cert. ¢ Highest No. of valid certificate is around

130 cert. in 1997-2000

Why to develop QSPSC?

¢ Because of ¢ Unstable concrete quality 20 years ago ¢ Hong Kong Housing Authority and some

Government Departments wanted to improve the concrete quality at that time

Contractual Relationship

¢ Developers did not have direct contractual relationship with concrete suppliers

¢ Contractors select concrete suppliers on their own

¢ Batching Plant may not be in the site area ¢ Concrete quality cannot be fully determined

during “Receiving Inspection”

Key Contractual Control

¢ Approval of Concrete Design ¢ Site Workability Test ¢ Compressive Strength Test (7/28 days) ¢ Non-destructive Test

Why QSPSC was developed by HKQAA?

¢ The purpose of setting up HKQAA was to assist industry & commence in the development of quality system

¢ HKQAA is a non-profit distributing organization

¢ HKQAA was formed by the Industry Department of Hong Kong Government in 1989 for ISO 9000 certification service
